What is Run This LLM?
Run This LLM is a lookup website for people who want to run AI models locally and need to know whether their computer can handle them. According to its homepage, it covers 295+ models across language, image, video and audio, and provides full build specs, performance estimates and benchmarks for each. The site offers two main paths: "I have hardware", which answers what you can run on your current setup, and "I have a model", which tells you what hardware a given model requires.
Beyond the search tool, the site offers a custom build service. Users describe the models they want to run, their use case (personal, software development, research, creative work, business or other) and a budget range from $3,000 to $50,000+, and the team says it will spec, build and ship a machine for those models. There is also a Chrome extension that shows hardware requirements in the browser sidebar, which the site describes as free.
